    • Abstract

    Background
    In a phase III trial in first-line, advanced NSCLC, nab-paclitaxel + carboplatin (nab-P/C) significantly increased tumor response rates, with comparable overall survival (OS) vs solvent-based paclitaxel + carboplatin (sb-P/C). However, nab-P/C improved OS in prespecified, stratified subgroups of pts, including those aged ≥­ 70 y (19.9 vs 10.4 mo; P = 0.009) and in North American pts, (12.7 vs 9.8 mo; P = 0.008). Based on the data from this trial, nab-P/C was approved by the US Food and Drug Administration (FDA) as a first-line treatment in advanced NSCLC, a condition for which no drug has demonstrated a clinically meaningful survival advantage vs platinum doublets in an unselected population in FDA registration trials. Here, we report results of a cost-effectiveness analysis that was conducted from the US payer perspective, with resource use data collected during the trial.

    Methods
    Cost-of-care estimates were applied to patient-level data on chemotherapy, drug delivery, patient monitoring, supportive care drugs, and treatment of dose-limiting toxicity. Cost-effectiveness outcomes were presented as incremental cost per life year ($/LY) gained with nab-P.

    Results
    Use of colony stimulating factors and treatment discontinuations due to toxicity were comparable between experimental and control arms. Taxane dose intensity was higher with nab-P vs sb-P (79.6% vs 61.8%). For all pts, the nab-P/C group had a $25,868 higher cost compared with sb-P/C ($35,179 vs $9,310) and an incremental $/LY gained in excess of $100K, comparable with $/LY gained estimates published for other recently approved NSCLC agents. However, in the subsets of pts aged ≥ 70 y and those from North America, the cost differential was reduced to $18,244 and $19,941, respectively. $/LY gained was reduced to $23,000 and $83,000, respectively, which compares favorably with published incremental $/LY gained for other NSCLC agents based on their OS advantage in patient subpopulations. Similar results were observed in a post hoc analysis of the subgroup of pts aged ≥ 60 y.

    Conclusion
    Weekly nab-P/C can be considered a clinically and economically attractive treatment option for US payers for first-line advanced NSCLC, particularly in the North American and elderly subsets. Future clinical trials are needed to validate these findings.
